1、湖北理工学院 毕业设计（论文） I 摘 要 液压技术自 18 世纪末英国制成世界上第一台水压机算起，已有 300 年的历史了，但其真正的发展只是在第二次世界大战后 50 余年的时间内，战后液压技术迅速向民用工业，在机床，工程机械，农业机械，汽车等行业中逐步推广。本世纪60 年代以来，随着原子能，空间技术，计算机技术的发展，液压技术得到了很大的发展，并渗透到各个工业领域中去。当前液压技术正向高压，高速，大功率，高效，低噪音，经久耐用，高度集成化的方向发展。 打包机又称捆包机或 捆扎机 ，是使用捆扎带缠绕产品或包装件，然后收紧并将两端通过热效应熔融或使用包扣等材料连接的机器。打包机的功用是使塑料带
2、能紧贴于被捆扎包件表面，保证包件在运输、贮存中不因捆扎不牢而散落，同时还应捆扎整齐美观。 关键词 ： 液压技术 ； 打包机 湖北理工学院 毕业设计（论文） II Abstract： Hydraulic technology since the end of the 18th century made the worlds first hydraulic press, counting more than 300 years of history, but its real development only in the 50 years after World War II, post-war
